CVE-2026-87838 Details
Description
The Wava Payment Plugin WordPress plugin before 0.3.10 does not perform any authorisation, nonce or origin verification on one of its public REST endpoints, allowing unauthenticated attackers to overwrite the stored credential that identifies the merchant account the store's payments are created against, to force the integration into a verified state the site owner never completed, and to remove the payment method from the store's checkout.
A vulnerability exists in the Wava Payment Plugin for WordPress, specifically in versions prior to 0.3.10. The issue arises because the plugin's public REST endpoint does not implement any authorization, nonce, or origin verification. This lack of security allows unauthenticated attackers to overwrite the stored credentials that link a merchant account to the store's payment system. Exploiting this vulnerability can force the payment integration into a verified state that the site owner has not completed, and remove the payment method from the store's checkout process.
Users are advised to update the Wava Payment Plugin to version 0.3.10 or later.
